Where, when, why, how?

The Mozambique Flood happened in February to March of 2000. The flood was due to heavy rainfall lasting five weeks, and it wiped out most of the vegetation in the area. The rain caused the banks of the Limpopo River to collapse, flooding the plains. The countries affected (besides Mozambique) were South Africa, Zambia, Zimbabwe, Botswana, Swaziland and Madagascar. It prompted many changes in the region's ecology and ecosystems, having affected vegetation, wildlife and humans living there.
